There is a log for i62/i62ML in Onyx International (China). I suppose it should be the same change log for M92 as were released simultaneously and Booxtor firmware are based in Onyx International.
But I think Booxtor should make it clearhttp://www.onyx-international.com.cn....php?serial=38

Well spotted, thanks for that! Any improvements to pdf-reading it welcome!

hey, is it possible to get other voices for the m92 and so yeah, how can you get these voices and how to install these voices on your ereader. I read somewhere about acapela, but really I have no clue how it works.

I think they are working on integratting Acapella and the Onyx Boox. In summer, Booxtor announced they planned to publish a beta version in a couple of weeks, but the suffered some delays. I hope we can test it soon! Meanwhile you can test the voices here: http://www.acapela-group.com/text-to...tive-demo.html

There is not agenda SW for M92, AFAIK. One user used the solution that scanned an agenda book (callendar) for a given year and converted it to pdf.

Then one might scrible in pdf agenda book as if it was paper one. It is also possible to download agenda books in pdf format from internet, so no scanning of paper one is needed, if those available suit you.
